METHOD OF MAKING BARBED FENCING.

SPECIFICATION forming part of Letters Patent No. 507,184, dated October24, 1893.

Application filed June 8, 1888. Serial No. 276,522. (No specimens.)

To all whom it may concern.-

Be it known that I, JOSEPH TEMPLIN, a citizen of the United States, anda resident of Reading, in the county of Berks and State of Pennsylvania,have invented certain new and useful Improvements in Methods of MakingBarbed Fencing, of which the following is a specification.

This improved method of making barbed metallic fencing consists ofproducing two barbed strips from one double blank strip by slitting itat intervals along the middle by two different ranges of slits whichslits are made in two parallel lines and two diagonal lines connectingthe parallel lines and the slits of each range are so reversed to eachother that the diagonal lines of one slit cross the diagonal lines ofthe other slit and out the points of the barbs, while the parallel linesextend therefrom each way the length of the barbs and out both edges ofthe body portions of them from the strips and complete the barbs and theseparation of the two strips. Then the barbs are bent laterally for therequired projection, and slight points left 'on the edges of the stripsby the diagonal cuts are left or trimmed off at the same time or priorto the bending if desired all as follows, referring to the drawings, inWhich Figure 1 represents face views of the slitting and bending dies.Fig. 2, represents a side elevation of the same with the blank stripbetween them. Fig. 3, is a diagram of the blank strip showing the actionof the dies on it, and Fig. 4 represents face views of the dies withother dies for trimming off the points left on the strips by theslitting dies between the diagonal cuts. Fig. 5 is a diagram of thestrip as cut by dies of Fig. 4.

By one operation and preferably the first in order of time, I make thetwo slits a, b, in the middle of the blank strip a, one a little inadvance of the other, which slits are partly in two different parallellines as wide apart as the width of the barbs to be made and partly inthe diagonal lines connecting the parallel lines, said diagonals beinginclined reversely to each other and the contiguous ends of the twoslits being in one line and the opposite ends of said slits in anotherof the parallel lines, with the uncut web 0, between the ends of theslits; and by another operation, preferably after the blank shifts alongone feed movement, I make another continuous slitf, of like characterbut longer than slits a, 6, combined, and being reversed thereto so thatits extremities are in the line of the contiguous ends of slits a, b,and its diagonals cross those of slits a, b, thus cutting four barbs h,and separating the barb strips 1, two of which barbs arejoined to onebarb strip j, by the web 0, left between the contiguous extremities ofslits a, b, and two others are joined to barb strip 2', by uncut webs 9,left between the opposite extremities of said slits a, b, the former byreason of the distance of the cutters apart and the latter through thefeeding of the blank as much more at each movement than the length ofsaid slits as is required for reserving said retaining webs.

The slits f, preferably extend as much beyond slits a, b, at one end orat both ends opposite web g, as is requisite to out through from slit toslit successively and makea continuous slit, but dies of equal length asthe two pairs 0, 10, may be used as in Fig. 4 with web cutters as w, tomake slits y, to separate the uncut webs that would be left oppositewebs g, which cutters may be located in advance as shown,'or insuccession of the others. Then Icause the barbs to be bent laterally tothe strips for the required projection either leaving the slight pointsZ, or at the same time trimming them off by the benders, which points Z,are left by the slitting cutters on the edges of the barb strips betweenthe points of the barbs, or the trimming of said 1 points may beeffected by slits n, that may be made before the cutting of the barbs ifdesired.

It is to be understood that the slit f, may be made first and slits a,1), next, the result being the same in either case.

The slits a, b, are made by two pairs of dies 0, p, and slit-s f, byanother pair q, s, or a single pair having a gap to leave web 0, may beemployed for the slits 0t, b,'if preferred. Two pairs of benders t, a,are employed to bend the barbs and they are arranged to bend themalternately in opposite directions; to, represents face views of cuttersemployed to make slits n, to trim oit the slight points Z, left betweenthe crossing of the diagonal lines, on which points of the barbs areout. These maybe arranged in advance of the rest of the cutters toaccomplish the work by making initial slits n, as represented in Fig. 5or they may be arranged for later action; but if desired the bendingdies may be adapted for such trimming at the same time they do thebending as represented in Figs. 1 and 2, or if desired the benders It,may be so shaped as that they will pass said points without effect onthem while bending the barbs.

WhatI claim, and desire to secure by Letters Patent, is-

1. The method of producing two barbed strips from one double blankstrip, which consists in successively making two slits at intervalsapart in the middle of the blank one a little in advance of the other,which slits are partly in two different parallel lines as wide apart asthe width of the barbs to be made, and partly in diagonal linesconnecting the parallel lines, said diagonals being inclined in reverseof each other, and the contiguous ends of the two slits being in oneline, and the opposite ends of said slits in another of the parallellines, and successively making other converse sli s of like form asthese two joined in one, with the diagonals crossing the diagonals ofthe said first two slits and the parallels in extension of theparalleleof the said first slits each way from the diagonals, and successivelymaking a continuous slit substantially as described.

2. lhe method of producing two barbed strips from one double blankstrip, each having laterally projecting barbs which consists insuccessively making two slits at intervals apart in the middle of theblank one a little in advance of the other, which slits are partly intwo different parallel lines as wide apart as the width of the barbs tobe made and partly in diagonal lines connecting the parallel lines, saiddiagonals being inclined in reverse to each other, and the contiguousends of the two slit-s being in one line, and

the opposite ends of said slits in another of a JOSEPH ,l-l. 'IEMPLIN.Witnesses:
